These projects encompass the construction of facilities to address water pollution, air pollution, solid waste, noise, and other issues, emphasizing technical, environmental, and ecological compatibility. Environmental engineering construction generates significant amounts of dust, and the significant amount of dust generated at construction sites is a major area of ​​environmental engineering work.

[0020] The present invention provides a dust removal device for environmental engineering construction with a filtering function. It has the following beneficial effects:

[0021] 1. The environmental engineering construction dust removal equipment with filtering function has a water trough installed on the top of the enclosure outside the environmental engineering construction site. The suction of the high-pressure water pump is used to suck out the water in the water tank, and the water enters the interior of the pipe under the transportation of the delivery pipe and is sprayed to the outside from the nozzle, so that the environmental engineering construction site can be dusted by spraying mist.

[0022] 2.

[0023] 3. The environmental engineering construction dust removal equipment with filtering function is installed just above the water receiving trough through a pipeline. As the nozzle sprays water outward, the bottom of the falling water droplets will fall into the inside of the water receiving trough, so that the water droplets can be gathered. Under the blocking of the baffle, the water collected in the water receiving trough passes through the through hole and enters the inside of the return pipe. Under the drainage of the return pipe, the water enters the inside of the water storage tank again, so that the water can be recycled and reused, realizing water circulation and saving water resources.

[0024] 4. The environmental engineering construction dust removal equipment with filtering function is detachably installed at the end of the pipe using a plug, and a detachably installed baffle at the end of the water receiving trough.

[0025] 5.

The water body is sucked by the liquid inlet of the high-pressure water pump, and the dust and debris can be filtered through the filter net to realize the filtering function, so that the separated debris will not enter the interior of the high-pressure water pump.

[0026] 6. The environmental engineering construction dust removal equipment with filtering function, under the suction of the liquid inlet of the high-pressure water pump, allows water to pass through the filter net, the flowing water contacts the impeller blades, and the fluid impacts the impeller blades. Under the impact of the fluid, and combined with the rotating support of the connecting shaft, the connecting shaft drives the toggle piece to rotate, which can drive the scraping teeth to rotate together, thereby scraping off the dust and debris attached to the surface of the filter net, keeping the filter net clean, and helping to filter the water.

[0027] 7. The environmental engineering construction dust removal equipment with filtering function uses a toggle plate to apply an upward toggle force to the roller, and under the connection of the right-angle rod and the connecting round rod, the spiral scraper moves upward. As the roller is separated from the toggle plate, the upward toggle force on the roller disappears, and under the elastic force of the elastic reset strip, the right-angle rod and the connecting round rod drive the spiral scraper to move downward. In this way, the spiral scraper can move back and forth up and down to scrape off the sludge sticking to the inner wall of the return pipe, so that the sludge falls off, which is not easy to cause blockage in the return pipe, further promoting the recovery of water in the return pipe.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0040] An environmental engineering construction dust removal device with filtering function, comprising:

[0041] A water tank 1, and wheels 2 installed at the bottom of the water tank 1, and a filtering mechanism 3 installed in the middle of the water tank 1;

[0042] The water supply mechanism 4 is used to collect and recycle water droplets and to spray water for dust reduction. The water supply mechanism 4 is installed in the middle of the top of the water storage tank 1;

[0043] The water supply mechanism 4 includes a return pipe 41 and a high-pressure water pump 42. The return pipe 41 is fixedly installed on the side of the top of the water tank 1. The high-pressure water pump 42 is installed on the top of the water tank 1 and away from one end of the return pipe 41. The top of the outer surface of the return pipe 41 is fixedly connected to a water receiving groove 43. A through hole 44 is opened at the position of the water receiving groove 43 on the outer surface of the return pipe 41. A spray mechanism 45 is installed inside the water receiving groove 43. A baffle 46 is detachably installed at the end of the water receiving groove 43 away from the return pipe 41 to block the water. A ball support 47 is rotatably mounted at the center of the plate 46, which is installed just above the water receiving trough 43 through a pipe 451. As the nozzle 452 sprays water outward, the bottom of the falling water droplets will fall into the interior of the water receiving trough 43, thereby gathering the water droplets. Under the blocking of the baffle 46, the water collected in the water receiving trough 43 passes through the through hole 44 and enters the interior of the return pipe 41. Under the drainage of the return pipe 41, the water re-enters the interior of the water storage tank 1 and is recycled and reused.

[0044] The return pipe 41 is installed vertically, and the bottom end of the return pipe 41 is connected to the top of the water tank 1. The water inlet end of the high-pressure water pump 42 passes through the top of the water tank 1 and extends into the interior thereof.

[0045] The spray mechanism 45 includes a pipe 451 and a nozzle 452. The pipe 451 is rotatably mounted on the surface of the return pipe 41. The pipe 451 passes through the center of the through hole 44 and is mounted directly above the water receiving trough 43. The nozzle 452 is mounted on the surface of the pipe 451. A rotating connector 453 is installed at the water inlet of the pipe 451. A delivery pipe 454 is installed between the rotating connector 453 and the water outlet at the top of the high-pressure water pump 42. A plug 455 is detachably mounted on the surface of the pipe 451 and at one end close to the ball head support 47. The fixing seat at the bottom of the water receiving trough 43 is mounted on the top of the enclosure outside the environmental engineering construction site. The staff starts the high-pressure water pump 42 to work, and uses the suction force of the high-pressure water pump 42 to suck out the water in the water tank 1. Under the transportation of the delivery pipe 454, the water enters the interior of the pipe 451 and is sprayed to the outside from the nozzle 452, so as to remove dust from the environmental engineering construction site by spraying mist.

[0046] The delivery pipe 454 is a hose, and the nozzle 452 is arc-shaped. The nozzles 452 are evenly distributed on the outer circumference of the pipe 451. As the high-pressure water pump 42 applies pressure to the water, the water is sprayed out from the nozzle 452. The nozzle 452 is arc-shaped and evenly distributed on the outer circumference of the pipe 451. Through the action and reaction force, the nozzle 452 is pushed in the opposite direction by the sprayed water mist, and the pipe 451 is driven. The pipe 451 is rotatably installed between the pipe 451 and the return pipe 41, and the ball head support 47 rotatably supports the plug 455, so that the pipe 451 rotates smoothly and is not prone to jamming. The nozzle 452 rotates along with the pipe 451, and the circumferential rotation of the nozzle 452 can be used to increase the spray range.

[0047] At the same time, the liquid outlet end of the delivery pipe 454 is rotatably installed by rotating the connector 453, so that the structure will not get stuck when the pipe 451 rotates.

[0048] One end of the ball support 47 away from the blocking piece 46 is in contact with the surface of the plug 455 , and the center of the plug 455 coincides with the central axis of the middle of the ball support 47 .

[0049] By using the plug 455 that can be detachably installed at the end of the pipe 451 and the baffle 46 that can be detachably installed at the end of the water receiving trough 43, the plug 455 can be removed and the pipe 451 can be spliced. The baffle 46 can be removed and the water receiving trough 43 can be assembled, so that the pipe 451 and the water receiving trough 43 are lengthened and can be assembled according to the specific conditions of the environmental engineering construction.

[0050] The second embodiment, based on the first embodiment, see Figures 1 to 7 As shown:

[0051] The filtering mechanism 3 includes a supporting baffle 31, which is fixedly connected to the middle of the water tank 1. A conical bucket 32 ​​is fixedly installed between the surface of the supporting baffle 31 and the water inlet at the bottom of the high-pressure water pump 42. A strip hole 33 is provided on the conical surface of the conical bucket 32. A filter net 34 is fixedly installed in the middle of the surface of the supporting baffle 31. A rotary cleaning component 35 is installed at the center of the filter net 34. As the return pipe 41 guides the recovered water into the water tank 1, and under the isolation of the supporting baffle 31, dust and debris will be mixed in the water. The water is sucked by the liquid inlet of the high-pressure water pump 42, and the dust and debris can be filtered through the filter net 34 to achieve the filtering function, so that the separated debris will not enter the interior of the high-pressure water pump 42.

[0052] The conical bucket 32 ​​and the filter screen 34 are installed at the same height, and the strip holes 33 are evenly distributed on the conical surface of the conical bucket 32.

[0053] The rotary cleaning assembly 35 includes a connecting shaft 351, which is rotatably mounted at the center of the filter screen 34. The outer cylindrical surface of the connecting shaft 351 is fixedly mounted with an impeller blade 352, and the impeller blade 352 is mounted inside the conical bucket 32. The outer cylindrical surface of the connecting shaft 351 and one end away from the impeller blade 352 is fixedly connected to a paddle plate 353. The surface of the paddle plate 353 and one side close to the filter screen 34 are fixedly connected to scraper teeth 354. Under the suction of the liquid inlet of the high-pressure water pump 42, water passes through the filter screen 34, and the flowing water contacts the impeller blade 352. The fluid impacts the impeller blade 352. Under the impact of the fluid, and combined with the rotation support of the connecting shaft 351, the connecting shaft 351 drives the paddle plate 353 to rotate, which can drive the scraper teeth 354 to rotate together, thereby scraping off dust and debris attached to the surface of the filter screen 34, keeping the filter screen 34 clean and tidy, and filtering the water.

[0054] The impeller blades 352 are evenly distributed on the outer cylindrical surface of the connecting shaft 351, the toggle pieces 353 are arc-shaped, there are three toggle pieces 353, and the three toggle pieces 353 are evenly distributed on the outer cylindrical surface of the connecting shaft 351 and away from one end of the impeller blades 352, and the scraping teeth 354 are away from the side of the toggle pieces 353 and are in contact with the surface of the filter screen 34.

[0055] The third embodiment, based on the first and second embodiments, see Figures 1 to 9 As shown:

[0056] An auxiliary component 5 is installed inside the return pipe 41. The auxiliary component 5 includes a right-angled rod 51, which is installed in the middle of the return pipe 41. The bottom end of the right-angled rod 51 extends to the inside of the water tank 1. A roller 52 is installed on the bottom of the right-angled rod 51. An elastic reset strip 53 is fixedly connected between the bottom of the right-angled rod 51 and the top of the inner cavity of the water tank 1. A connecting round rod 54 is fixedly connected to the top of the right-angled rod 51. A spiral scraper 55 is fixedly connected to the end of the connecting round rod 54 away from the right-angled rod 51. The toggle piece 353 is driven to rotate by the connecting shaft 351, and the roller 52 is used to contact the toggle piece 353, so that The toggle piece 353 applies an upward toggling force to the roller 52, and under the connection of the right-angled rod 51 and the connecting round rod 54, the spiral scraper 55 moves upward, and the elastic reset strip 53 is squeezed and elastically deformed. As the roller 52 disengages from the toggle piece 353, the upward toggling force on the roller 52 disappears, and under the elastic force of the elastic reset strip 53, the right-angled rod 51 and the connecting round rod 54 drive the spiral scraper 55 to move downward. In this way, the spiral scraper 55 can move back and forth up and down to scrape off the sludge stuck on the inner wall of the return pipe 41, so that the sludge falls off, which is not easy to cause blockage of the return pipe 41, thereby promoting the recovery of water by the return pipe 41.

[0057] The right-angled rod 51 passes through the center of the return pipe 41 , the elastic reset strip 53 is arc-shaped, the spiral scraper 55 is evenly installed inside the return pipe 41 , and the spiral surface of the spiral scraper 55 fits the inner wall of the return pipe 41 .

[0058] When in use, first install the fixing base at the bottom of the water receiving tank 43 on the top of the enclosure outside the environmental engineering construction site, and fill the water tank 1 with water;

[0059] At this time, the staff starts the high-pressure water pump 42 to work, and uses the suction force of the high-pressure water pump 42 to suck out the water in the water tank 1. Under the transportation of the delivery pipe 454, the water enters the interior of the pipe 451 and is sprayed to the outside from the nozzle 452, thereby removing dust from the environmental engineering construction site by spraying mist.

[0060] As the high-pressure water pump 42 applies pressure to the water, the water is sprayed out from the nozzle 452. The nozzle 452 is arc-shaped and evenly distributed on the outer surface of the pipe 451. Through the action and reaction force, the nozzle 452 is pushed in the opposite direction by the sprayed water mist, and the pipe 451 is driven. The pipe 451 is rotatably installed between the pipe 451 and the return pipe 41, and the ball head support 47 rotatably supports the plug 455, so that the pipe 451 rotates smoothly and is not prone to jamming. The nozzle 452 rotates along with the pipe 451, and the circumferential rotation of the nozzle 452 can be used to expand the spray range.

[0061] The liquid outlet end of the delivery pipe 454 is rotated and installed by rotating the connector 453, so that the pipe 451 rotates smoothly without getting stuck.

[0062] At the same time, as the nozzle 452 sprays water outward, the bottom of the falling water droplets will fall into the inside of the water receiving trough 43, thereby collecting the water droplets. Under the blocking of the baffle 46, the water collected in the water receiving trough 43 passes through the through hole 44 and enters the inside of the return pipe 41. Under the drainage of the return pipe 41, the water enters the water storage tank 1 again and is recycled.

[0063] As the return pipe 41 guides the recovered water into the water storage tank 1 and is blocked by the support partition 31, dust and debris are mixed in the water. The water is sucked in by the liquid inlet of the high-pressure water pump 42, and the dust and debris are filtered through the filter net 34, thus achieving the filtering function and preventing the separated debris from entering the interior of the high-pressure water pump 42.

[0064] Under the suction of the liquid inlet of the high-pressure water pump 42, water passes through the filter screen 34, and the flowing water contacts the impeller blades 352. The fluid impacts the impeller blades 352. Under the impact of the fluid, combined with the rotation support of the connecting shaft 351, the connecting shaft 351 drives the toggle piece 353 to rotate, which in turn drives the scraping teeth 354 to rotate together, thereby scraping off the dust and debris attached to the surface of the filter screen 34, keeping the filter screen 34 clean and tidy, and filtering the water.

[0065] Moreover, the toggle piece 353 is driven to rotate by the connecting shaft 351, and the roller 52 is brought into contact with the toggle piece 353, so that the toggle piece 353 applies an upward toggle force to the roller 52, and under the connection of the right-angle rod 51 and the connecting round rod 54, the spiral scraper 55 moves upward, and the elastic reset bar 53 is squeezed and elastically deformed. As the roller 52 disengages from the toggle piece 353, the upward toggle force on the roller 52 disappears, and under the elastic force of the elastic reset bar 53, the right-angle rod 51 and the connecting round rod 54 drive the spiral scraper 55 to move downward. In this way, the spiral scraper 55 can move back and forth up and down to scrape off the sludge stuck on the inner wall of the return pipe 41, so that the sludge falls off, which is not easy to cause blockage of the return pipe 41, thereby promoting the recovery of water by the return pipe 41.
